What the Data Shows
Five major UK new-car powertrains are tracked annually from 2019 to 2025. Each line uses cars registered for the first time in the calendar year, with petrol and diesel variants combined within the hybrid groups. Battery-electric registrations rise from 38,007 in 2019 to 473,225 in 2025, a 12.5-fold increase. Diesel moves in the opposite direction, falling from 622,089 to 95,838 over the same period.
